Formulas: KE=½(m)(v)2 Kinetic Energy = one half of the mass times the velocity squared GPE=(m)(g)(h) Gravitational Potential Energy = mass times gravity times height EPE=(k)(x)2 Elastic Potential Energy = elasticity constant times the deflection squared W= (f)(d) Work= force times distance Units: m (mass) if you are finding a mass it should be in Kg if you are given a mass that is NOT in Kg you need to convert it to Kg v (velocity) if you are finding the velocity your answer should be in m/s h (height) if you are finding the height your answer should be in meters (m) if you are given a height that is NOT in meters, you need to convert it to meters! k (elasticity constant) this is the number that represents how elastic or bendy something is. It is measured in n/m or newton's/meter x (deflection ) deflection is a measurement of how much an object is bent from a straight position. It is measured in meters (m). If it is NOT in meters then you need to convert it to meters Kinetic Energy (KE), Elastic Potential Energy (EPE), and Gravitational Potential Energy (EPE) are all measured in joules (J). W (work) is measured in joules (J) just like energy! f (force) is measured in Newtons (N) d (distance) measured in meters. If it is NOT in meters then you need to convert it to meters
